Local sublattice-symmetry breaking in rotationally faulted multilayer graphene

arXiv:1009.4492 · doi:10.1103/PhysRevB.83.045425

Abstract

Interlayer coupling in rotationally faulted graphene multilayers breaks the local sublattice-symmetry of the individual layers. We present a theory of this mechanism, which reduces to an effective Dirac model with space-dependent mass in an important limit. It thus makes a wealth of existing knowledge available for the study of rotationally faulted graphene multilayers. We demonstrate quantitative agreement between our theory and a recent experiment.
